CHIMNEY FOR OIL-BURNING COOK-STOVESl Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed March 19, 1920. Serial No. 367,031.

T 0 all whom it may concern Be it known that I, FRANcIs J. PRIDEAUX, acitizen of the United States, resident of Adrian, county of Nobles,State of Minnesota, have invented certain new and useful Improvements inChimneys for O1l-l3urning Cook-Stoves, of which the following is aspecification. T

In the operation of the well-known o1l burning stoves for cookingpurposes, usmg one or more burner flames, it has been discovered that incooking or roasting meats or other articles of food there frequently isinsufficient heat in the burner directly beneath the kettle in which thefood may be cooking to cook it as rapidly as desired and difliculty isalso experienced when a boiler is placed over two of the burners andwater is being heated for clothes washing purposes.

The object of my invention, therefore, is to provide a flue connectionbetween contiguous chimneys by means of which two burners may be coupledtogether and the heat delivered to the one chimney over which the kettleor other cooking utensil may be placed.

A further object is to provide an attach ment which can be easily andquickly adapted for the metal chimneys in general. use on stoves of thistype.

Qther objects of the invention will appear from the following detaileddescription.

The invention consists generally in various constructions andcombinations, all as described and particularly hereinafter pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a front elevation of an oil burning cook stove embodying myinven- Fig. 2 is a detail view showing the different positions in whichthe damper located in the flue may be adjusted,

Fig. 3 is a sectional view on the line 3-8 of Fig. 2.

Fig. 4 is a view of the cover removed from the chimney.

In the'drawing, 2 represents the base of the stove, 3 is the bodyportion thereof and 4 the top, having the usual openings 5 on which thecooking utensil is placed. 6 represents a suitable reservoir for thefuel oil, 7 a pipe leading therefrom and 80m of a plurality of burnerscommunicating with a considerable saving in time.

the pipe and above which the well known metal chimney 9 is mounted,having adoor 10 through which access may be had to the burner. All thismechanism is of ordinary construction and in general use in stoves ofthis type.

For the purpose of enabling the cook to utilize the heat of two burnersin one chimney, I provide contiguous chimneys with pipe sections 11 and12 fitted over openings formed in the chimneys and having their endsarranged to telescope, stove-pipe fashion, as indicated by the dottedline in Fig. 2. These pipe sections, when joined together, form a flueleading from one chimney to an adjoining one, and the flue is preferablyupwardlyinclined so thatthe heat from the burner of the chimney to whichthe pipe section 12 is attached will be directed throughthe pipe section11 to the adjoining chimney. A damper 13 is provided in the pipe section12 and as a hinge therefor I prefer to provide a rod 14 mounted in thewall of the pipe 12 at its intersection with the chimney and having aloop portion 15 to which the damper 13 or valve is connected. A crank 16is mounted on the shaft 14 and has an operating handle 17 and is adaptedto move over a rack 18 having notches therein for engaging the crank 16and holding the damper in any of its adjusted positions. For instance,referring to Fig. 2, the full line position shows the passage to theflue entirely cut ofi, while in dotted lines I have shown the passagethrough the chimney partially and entirely closed. When this passage isentirely closed,

and 12 into the chimney adjoining and combined with the heat of theburner in this chimney, will very rapidly cook the contents of theutensil above. These flue sections may be made of. any suitable gage ofsheet metal and may be enameled, if preferred, to I correspond to thefinished surface of the metal chimneys.

In addition to doublin the amount of heat for cooking purposes, I havefound that water in a wash boiler can be heated with Stoves of this typeare of such construction that a wash boiler when placed on the top ofthe stove will cover two of the adjoining chimneys. With my attachmentthe third chimney will be included and the heat of three I combined inone chimney, if desired, and in be multiplied and still various ways theuse of the attachment may be within the scope of my invention. a j

I prefer to provide a removable ring 19 adapted to fit the top of achimney for use when the chimney is connected with one 'burner'only.When, however, a chimney is coupled up with an adjoining one so that theheat of the two chimneys is combined in one, I may remove this ring toprovide a larger orifice in the top of the chimney.

In Fig. 2 I have shown the ring in place on one of the chimneys andremoved fro the other chimney.

I claim as my invention:

lxThe combination, with a stove having burners and a chimney extendingupwardly from each, of a flue connecting one chimney with an adjacentchimney above the burners thereof for conducting the heat from oneburner into the chimney of the adjacent burner.

2. The combination, with a stove and its burners and chimneys thereforprojecting incline to connect adjacent chimneys above the burners, theupper end of the flue being adjacent to the upper end of the chimneywith which it is connected, and a damper mounted to intercept the heatpassing upwardly in one chimney and deflecting it through said flue tothe chimney of the adj acent burner.

3. The combination, with a stove, burners and the chimneys thereof, of aflue mounted to connect one chimney with another above the burner andhaving means for simultaneously closing one chimney and directing theheat of the burner inlsaid one chimney through said flue into the otherchimney to supplement the heat' from the burner of the latter chimney.

4%.. The combination, with an oil burning cook stove having burnersandchimneys extending a considerable distance above the burners and astove top above the chimneys having openings therein for the cookingutensils, of a flue between the burners and the stove topand leading'from'one chimney V to another, and a single damper mounted to FRANCISJ.
